Patent GB-971162-A (GB)
Title: Injection inoculation instruments
Inventor: HOGG CHRISTOPHER ALAN
IPC: A61M5/28
Filed: 1961-11-21
Abstract: 971,162. Valves. BRITISH OXYGEN CO. Ltd. Feb. 21, 1963 [Nov. 21, 1961], No. 41627/61. Heading F2V. [Also in Divisions A5 and F1] A jet inoculation instrument of the type which derives the pressure for jet injection from the admittance of a gas under pressure into a chamber associated with a plunger movable to pressurize a body of the inoculant, is provided with a pressure-operated valve to prevent the admittance of gas into said chamber if the gas pressure is below that required for satisfactory injection of the inoculant. As shown, the instrument comprises jet inoculation instrument A and gas dispensing device B which may be the device disclosed in Specification 971,161. The pressure-operated valve comprises valve seat 118 and member 120 attached to plunger 121 slidable in bore 122 of piston 112, and urged towards valve seat 118 by adjustable screw 124 and spring 123. In use when compressed gas container 4 is screwed on member 1, point 6 of piston 5 pierces container 4 but no gas is allowed to escape until actuator 2 is depressed. On depression of actuator 2, cam 9 rotates and allows piston 5 to rise under the action of spring 8. Gas enters inlet in instrument A and if the gas pressure is great enough, valve member 120 is moved against spring 123 away from seat 118 and gas enters chamber 117 and exerts a force on piston 112, which force is transmitted by plunger 111 on to ampoule piston 110 which pressurizes ampoule 109 causing the ampoule to rupture and the contents thereof to be ejected. Other types of ampoules may be used, e.g. an ampoule with a diaphragm designed to be pierced by a needle or a refillable ampoule. After injection the actuator 2 is released and this causes the opening of gas relief valve 10 to allow the release of gas trapped in the outlet of the dispensing device B and in the instrument A. On the release of gas pressure in inlet of instrument A the piston 112 is moved back under spring 115 and the gas in the chamber 117 is released through the inlet and valve 10 until the valve member 120 rests against seat 118. Any gas now remaining in chamber 117 is released through a non-return valve. This valve (see Fig. 2) takes the form of a rubber disc 128 normally pressing against rib 129. If the gas pressure in chamber 117 is greater than that in the inlet of instrument A, the disc 128 is forced away from rib 129 and gas passes from chamber 117 to valve 10 via passages 133 and 130 and the inlet of instrument A.

Each blade 6 consists of a frame 11, approximately rectangular to which are welded a plurality of parallel rods 12, bent to form a spoon, the spaces 13 between the rods 12 serving to drain the cuttings as the arms rotate. As each arm 5 approaches a vertically upward position, the cuttings slide from the blade 6 into the shoot below and thence into the next compartment, the bottom edge of the shoot being bent backwards slightly to assist the water in the shoot in draining back into the compartment from which it was raised. When the cuttings are discharged into the compartment 3a they fall on to a conveyer 16 or a further shoot which removes them from the washer, the conveyer being perforated for drainage. Water leaves the trough via orifice 8, in front of which is provided a grating. Preferably, at least one blade in the compartment 3c is provided with or replaced by a brush, &.c. for clearing cuttings from the grating. An alternative embodiment, Fig. 3 (not shown) has flat blades, with a part-cylindrical, perforated retaining wall (17) provided at one side of the path described by the blades, having the same width as the blades and extending to the vertical plane through the shaft, so that the cuttings slide round the wall (17) to the highest point and then drop into the shoot.

Abstract: 949,876. Hydraulic reciprocating motors; hydraulic apparatus. CESSNA AIRCRAFT CO. Nov. 29, 1961 [Jan. 12, 1961], No. 42679/61. Headings FIA and F1P. In an hydraulic motor comprising a piston 61 reciprocable in a cylinder 59, the piston speed is controlled by means comprising a restriction 64 in an outlet duct 4 and a shuttle valve 9, 70 sensitive to the pressure differential across the restriction and arranged to maintain a predetermined limit to volume flow through duct 4. In operation, when piston 61 moves downwardly, the pressure beneath it acts on the left-hand end of shuttle 9 via passage 15, the pressure on the downstream side of restriction 64 acting on the right-hand end of shuttle head 70 via passages 5, 12, 14, 18. When the pressure differential between chambers 16 and 18 is sufficient, the shuttle moves to the right against an adjustable spring 17 until control surfaces 20, 22 of shuttle 9 and a passage 6 co-operate to restrict flow through a notch 21. Cushioning of piston 61 at the end of its stroke is effected by the entry of projection 62 into passage 4 to further restrict flow, a portion 71 finally sealing the passage and spring 17 returning the shuttle to the left. For the return stroke, fluid pressure is supplied to cylinder 63 via passages 8, 7, 6, 5, 12 and check valve 13. In an embodiment for the piston rod end of the cylinder, cushioning of the piston is effected by its engaging a perforated piston valve the flow through which is progressively restricted as the piston moves upwardly.

Abstract: 1438573 Vehicle safety device G B HALLBERG 13 Sept 1973 [19 Sept 1972 2 Oct 1972] 43169/73 Heading B7B In a vehicle safety device an elongated gas sealed envelope mounted under the instrument panel is moved rearwardly by a first pressurized gas source against a vehicle occupant, a second pressurized gas source being adapted to inflate the envelope during its rearward movement. As shown in Fig. 1 the envelope comprises hoses 31 connected at one end to a T-piece 27 mounted on a slide 24, Fig. 3, and at their outer ends to a slide 44, Fig. 7, which travels in track sections 40, 41, mounted on the side wall 38 and the door 39 of the vehicle. Upon a vehicle collision a release apparatus (2), Fig. 2 (not shown), causes detonator means 18, 50, Figs. 4, 7, respectively to blast powder charges 17, 49 so that a piston 20, Fig. 4, is forced backwards in a central sleeve 6 and by means of the rod 21 the slide 44 and T-piece 27 are thrown backwards, the slide 24 travelling along a slot 29 in the upper part of sleeve 5. Simultaneously each of the piston-rods 45, Fig. 7, impacts the slide 44 which is thrown backwards along tracks 40, 41 so that each hose 31 is thrown backwards against the vehicle occupants. During this backward movement the hoses are untwisted about their longitudinal axes by means of a gear wheel 56, Fig. 8, rotatably mounted on the slide 44 and which engages a rack 57 mounted below the track 40. A plate (73), Fig. 2, extending from the instrument panel 12 guides the hoses past the lower edge of the steering wheel. When the hose 31 has passed the lower edge of the steering wheel, a pin 34, Fig. 3, is pushed upward by a cam portion 36 in sleeve 5 to detonate a powder charge 37 in T-piece 27, so that the blasting powder damages tubes 30, Fig. 5, containing freon gas which inflates the hoses. When the two slides 44 are in level with the shoulder of the occupant they are stopped by the tension in the hoses 31 and forward movement of the slides is prevented by a wedge shaped brake block 54, Fig. 7, which wedges firmly against the inside of track 41. The ends of two belts 62, 63 are attached to an ear 61, Fig. 5, on the T-piece 27, and the belts extend over a roller 64, journalled in a yoke 13, and through a ring 65 suspended on the slide 24. From the ring the belts are loosely suspended in bights on the hoses 31 and their rear ends are secured to a mounting 69, Fig. 1, on the inside of the door. An elastic element 68 on side wall 38 maintains the belts in a horizontal position. On backward travel of the slides 24 the belts 62, 63 freely slide through ring 65 and over roller 64 to be stretched over the hip portions of the vehicle occupants.
